'No sonata 1 T al lwkom a may Be itlknown that I Cimnws I. S'rsNsoN, a citizen of the United States, residing at Lynn, in the county .of Essexiand State of Massachusetts, have invented Channeling-Machines, of which the following description, in. connection with ,the accompanying drawings, isa specification, like letters on the drawings representing like parts. v

'ihis invention in channeling machines relates more particularly to-machines for channelihg the outsoles of boots and shoes after said soles have been .laid or preliminarily securedin position upon the shoe preparatory to stitching or otherwise fastening the same permanentlyin place. 1 It is common in the art to channel outsoles before they are laid or applied to and to. form a part of a shoe.

but an objection to this method is that the outline of the sole'and consequentlythat of the channel which is usually formed therefrom, does not'follow uniformly the outlineof the lasted upper, because of the difiiculty experienced in lasting the uppers uniformly, and also because of variations in thickness and texture of the stock employed. To overcome these objections, what is known as'the roughuoundingand channeling? '26 machine was devised, which was used upona block sole after the latter was laid upon the shoe tochop away the .ma.rginal pOlftldllJhBlGjOf along an outline intended to follow or be graded from'the outline of the lasted' upper and to channel the sale at the same time.

These machines,- however, are most difiicult to operate,

and do not give uniformly satisfactory results. B cause of the objections tothis lastnamedmachine, manufacturers have used quite extensively what known as the Arnold channeler, which isa machine adapted to operate upon the sole after it hasbeen died I out and laid .to channel said sole. at a desired distance Jinward fro in the-sole outline, this-distance being as a rule'greater alongthe shank portion of the sole than- The 4x11101111 0118.11-

about'the fore part thereof. 1Q neler, however, is& hand operatedmachine requiring ,skiliul operation, and at best has but a limited capacity find is expensive to kee p in repair and running order.

Myinvention aims to'produce a machine adapted for the class of work for which the Arnold channele'r has-heretofore been used'ybut which shall be power opgrated, so asto leave the operator free. with both his .hands to manipulate the shoe during the channeling I operation.

The'various features comprising my invention will Ml be best understood from a description of one embodi- *Inent thereof. ..1 Q 1 Inthe drawings forming a part of this specification, .13 igure 1 is a side elevation of arnachine illustrating one :embodiment of ,my' invention; Fig. 2 is a top or plan Specification of Letterl Estonia. 7 .A ums nts A ril 6.1906; BOX'lLl Nth 810,005-

I 'view of 1; Fig. 3 is a detail. in front elevation of the work= feeding and channel cutting devices; Fig.

4 is an enlarged sectional detail of the devices shown in Fig. 3, viewed, however, from the left, 'insteadof froxnrthe front; Fig. 5, asectiona-l plan view showing the column, base, and treadlearrangement; and, Fig. 6, a side elevation of the parts shown in Fig. 5.

In the particular embodiment of my invention selected for illustration herein and shown .ii1.the drawings, referring first to Fig. .1, the machine head A has suitable bearings for the horizontal main or drive shaft t1, provided at its-front end with a bevel gear a in mesh with and driving a bevel gear a, fast on the'lower end of a vertical shaft a journaled in the overhanging front end of the head.- Fast upon this shaft is a spur wheel a, in mesh with an intermediate 0, which drives an obliquely positioned 7 'work table or rest a, loosely I mounted upon a stud 'a in the head. The edge of this work supporting wheel a? is beveled so that it may prei sent at its highest point a substantially horizontal or level work supporting faceand immediately back of and above this face is'ahorizontal feed wheel b, loosely mounted upon a stud 'b .in the front of the head, the 1 :hub of said feed wheel being provided with a. spur wheel bi, driu'en' from'an intermediate b", by and from a spur-wheel b fast upon the upright shaft a. Thus,

the work supporting wheel a. and the feed wheel I; are

driven at desired speeds from the common main shaft 4.

In alinement withthe active points of the work supporting and feed wheels, but somewhat in front thereof is the channeling knife c, adj ustably mounted in the lower end of the knife ca'rrie r' c,.mounte d to slide in vertical bearings c",-in an arm 6, rising frd'mthe ma.- chine head. The reduced shank or stem of this knife slide'is encircled by a spring c,.'seated at its upper end against the outturnod end of said arm 0" and at its lower end upon a nut c, adjustably mounted upon a threaded portion of the knife carricr shank.- To raise and ,lowcr this knife mrrier for introduction and removal of the work, I have provided a lever (l, fulcrumed upon the head at d, engaging at its forward cnd the said knife carrier and at itsrcar end piovid'ed witha depending I actuating rod 114 Depression of this red J, as-by a rod permitting the spri ng c to depress the knife to its lowermost position or upon the work. e

the downward newness ofknife carrier -by .contact with'th'e sole, and erefore limits or determines the depth of cut of the channel. I

treadle, liftsthe knife bladeand its knife; releasebfisaid v v v .100 The lower end of the knife carricr is provided witha 4 prcsser e, adjustably mountcdthereon and which limits t operative to rotate it. To this end it may be mounted I power or solely by the contact of the work therewith;

shaft f, mounted upon the side of said arm 0 and adjustable as to its angle thereon about a center-f shown in dotted lines, Fig. -2, and in dotted linrs, Fig. l.

This bearing wheel is intended to assist in the feed of the work, and should always work freely, that is, without requiring any appreciable effort on the part of the to rotate with the utmost freedom in or on itssupporting hearing, or it may be provided with means for rotating it independently of the contact of the work said bearing wheel rotateswith' substantial freedom from resistance or effort communicated to it by the. work and assists in directing the work to and against the feed wheel v For operating the machine the operator through the lever d lifts the channel knife carrier and its knife and presser and inserts the usual extension of sole, as indicated, Fig. 4, over and upon the work supporting wheel a and with the edge of the sole bearing firmly against the feed wheel b. In order to bring the sole 'to an approximately level position with its edge thus bearing against the feed wheel, it is necessary for the operator to lift or turnthe shoe bodily about what maybe called a fulcrum point at the point where the solercsts upon the supporting wheel a, and thus lift the bearing wheel f against the action of its spring, the parts then being as indicated inFig. 4. While the weight of the bearing wheel and its shaft and the action of the driving con nections therefor under some conditions would be sufficient to maintain it in operative contact with the work yet in practice I prefer to employ a spring encircling the bearing wheel shaft f and marked'fjin Fig.2, said spring being seated at its upper end against the bearing in the yoke f E, and at its lower end against a nut f adjustably mounted on'said ehaft. The operator now drops the channeling knife upon the sole and starts the machine and simultaneous 'rotation of the work supporting wheel a and feed wheel b act to carry the sole and the shoe along in the direction of feed .past the channeling knife, which, under the action of its depressing spring c, buries itself into the substance of the soleand thereafter cuts a channel the depth of which is determined by the adjustment of the presser e, which rests A ribs b whichextend transversely of the feeding wheel and preferably parallel with the axis thereof.

The operation of feeding the shoe through the machine, which might under some conditions be accom- -plished with some difficulty becauseof the irregular outline or'profile' of the sole, is much facilitated by vii '1--- with, tends by 'its rotation, wheth'er driven-from contact of the sole therewith or. from a separate driving mechanism, to swing the approalching portions of the tact with which is essential for accuratework. This bearing wheel of course rises and falls to accommodate itself to 'the varying shape and level of the sole, and its beveled and rounded edge portion permits it to sole inward towards and against the feed wheel, confall readily into and rise from the shank portion of the shoe as the tool enters upon and leaves the-same,

To vary the distance of the channel inward from the edge of the sole, the arm (5, which carries the channel knife carrier, the presser, and the bearing wheel pressed normally toward the front of the machine by a spring g seated at one end against said head arm, a and at its opposite end against a nut g adjustably mounted on said stem, the forward springactuated movement of the slide being limited by a nut g,'.

threaded upon the rear end; of said stem and acting against the rear face of said head arm a r V In front of the spring supporting nut g and preferably acting against a washer there placed, is the upright arm of a bell crank lever g, fulcrumed in 'the head at g.'and having its horizontal arm provided with .an operating rod g, by which said bell crank lever may be moyed' tofdraw the knife carrying slide rearwardagainstthe action of said spring 9 to bring the channeling knife nearer to the feed wheel, thereby to cause the channel to'be cut nearer to the 'edge of the sole, said spring g'-, being sufliciently strong to return said channeling knife toward orintor-its normal and' most remote position-relative to the sole edge whenand as the rod g? is 'r 'l' a d, I

Referringnow to Figs. 5 and (i the supporting column I i B for the machine is provided :with two treadles v D and G, the treadle D- being connected-withhndto operate the rod d, previously describedas operating the lever d to raise and lower the channeling knife and prosser, while the treadle G -is connected with the drop rod 9 which operates the bell crank to vary the, in and out position of the channel knife.

In operating the machine the operator first depresses the treadle D raise the channel knife and presser to permit introduction of the work, and, as

- the cutting progresses around the sole, changes his foot to the other treadle G, "to varythe position of the channel relative to the-sole edge. I

In machines of this type it is desirable. that the feed: be at all times under'the. control of theoperator,-for, if the feed is uniform-with the-maximumspcedpossible along the straighter portions of..tho soleedgedifficulty is experienced in turningsharp toes or'entering and leaving the shank, and :if the speed is na'desuch that these more difficult portions of the sole may be handled with-safety, then the entireoperation becomes slower than is desirable or necessary. To accomplish what is desired in this respect, I have mounted the head to slide inward andoutward on and relative to the column B and to enable the head to be moved very easily in this direction, I prefer to employ -roller or ballbearings,

typified at m, 1; Upon. the rear end of the main shafta, and thus movable toward and from the operiator ,by and with the head A, is a friction driving member, shown as a flat faced disk or'wheel 0. Opposed I '5 to this in tion d isk is a belt pulley which may have one or a lity of belt faces of different diameters, as the manufacturer may desire, said belt pulley being frnodnted upon a sleeve surrounding the projected end of the main shaft a and 'having-its'own bearing in an 9?,xtended upward from the column. collar upon, the rear end of said sleeve confines said belt pulley against iront,to back movement by and with ll-the head, consequently, the head as a whole with its r friction disk, may bemovedbodily, rearward or away .15 from the operator, to bring the friction disk into driving contact with the belt pulley to receive rnotion therefrom to operate the machine, or, it may be drawn j to the iront 'of the'machine or toward the operator to separate said diskjrom the belt pulley to arrest the.

operation of the machine. 'To 'throw the head normally toward the front and theoperator, so as to' leave the machine normally at rest, I have provided a spring 0, (Fig. 1), thetension of which be adjusted at will, but which should be merely strong enough to disengage the drive and the feed without upon the I operator too much labor machine. I The operation ofithis devicefis this: the operative to compress it for-operating the having introduced the'work; presses the same 3.0 theifeed wheel'b, and this sets the entire head rearward sufficiently to bring the friction disk into engh gement with the belt wheel and start the machiue, and, so long.

as the operative maintains the-work pressed firmly againstthe feed wheel (which is necessary for accurate and. uniform feeding) during'jusfisuch timewill thedrive remain operative to'feedthe work. Upon ape :proaching a sharp toe or other dilficult" portion of the sole outline to be .channeled,-such, for instance,1is in" -.entering upon or leaving the shank, the operative by,

- 4 0 slackening up on the inward or pushing pressure 'im-' mediately stops, or, at his choice,- reduces. the feed, according to the degree of separation of the'jfi'i ctionjdisk from the belt'pulley, so that he ma stall times have an opportunity tov take a new hold upon the shoe, or; to slow up the feed for the better of the difli cultportions of the channeling operation. '1' g The machine-above simple'fn construe tionfhud the mode or handling'it-may be many .fquiredby a new operative, who, atno'time', need be an expensive operative.
